Can we get parts for the 64" big screen anymore? VS5078
I was told that my 64" TV has a power part out yet nobody makes parts for this TV anymore. Are there generic parts out there that can be used in its place. Paid $4,500 for this TV I don't want to just throw it out.

(See the comment I added to the comment section regarding your 2 volt output)... Without using the remote, press the power button on the TV itself and HOLD IT DOWN until the TV powers on. If that works, it is a (going) bad power amp chip. The good news is that if it works, it will work that way for quite some time, just so long as you are consistent with holding down that power button _until_ the TV powers on. Every time it fails to power on (such as when using the remote and/or momentarily pressing the power button), the chip fails further. In other words, the more times it is allowed to NOT "power on" the closer you get to total failure. So, if holding the power button until "power-on" works, make sure nobody does it the "not-working" way anymore. (Hope that makes sense because it really will matter). The cost of repair is not worth it. If all the above does not apply, you can check for a blown fuse in the TV's power supply. However, I can assure you there will be a (not worth fixing) reason for a blown fuse in the first place. BTW, I had a two JVC TV's with the "power-on" problem as I described above. I threw them away 2 years later _still_ working the way I described to you.
How long u have this RCA analoge tv?Around 10 years or more and used it like about 5 or 6 hrs everydays?Yes,than ur tv it is losing CRT tube radiation cohetion.As times go bye years in years out the tv CRT-(tv tube) radiation will slowly dying out,Tv actual pictures will lost some of it luster and it brightnesses to the tv auctual pictures.Brightnesses of CRT tube will get darker and darker until the tv actual pictures barely it is watchable anymore.Contrast,Brightness and Colors adjusting more will help some.But u have to take this tv aparts and take a Flat scerw driver turn up a little bit more of the tv HV-(high voltage) SCREEN button on the FBT-(flyback transformer) to make any big differences of the CRT tube brightnesses.The FBT-(flyback tranformer) is the big block of plastic with a red wire with a black cap hook up to the tv CRT-(tv tube).This adjustment on of the FBT,HV-SCREEN button will help the tv CRT-(tv tube) last another year or two.
No.The tv video board have dead components,that the board where it is connected to the CRT-(tv picture tube).Troubleshooting that video board and changes parts should fix ur tv problems.Hope ur tv problems,it is not the video board main big IC colors processor inverter.This big IC is a pain to change and probally not in the market anymore.Troubleshoot test all the capacitors around that big IC colors processor inverter alot of times just those few capacitors are dead only.
You have a bad eeprom. Very common problem for this TV. The replacement eeprom [location, IC002, on the Tv board] is dependent on which microprocessor [location, IC001, on the TV board] and which stereo decoder [IC 1001] are present on the board. See if IC002 has a color mark on it. red, yellow, green..etc. Or give me the numbers on the actual IC 001 and Ic1001. For example IC 001[ microprocessor] might beMCU A22V01-TO and IC 1001 [stereo decoder] MSP3440. Take this info to a TV tech if you cannot repair this TV yourself. Thanks for asking and give me a High Five of hands!
FBT,The flyback transformer it dead.Ur high voltage is dead.The FBT,the big black block of plastic with a red wire with a cap hook to a CRT(tv tube).Take to the repairman,might not have part anymore,because CRT analog tv.Tv compannies don't produce parts anymore.
you have a short in power supply the light should stay on check all power supply parts
you need to test all parts, i could fix this in
need help call 0403960527 jeff......
Even with the tv turned off, the power supply is still active.It's supplying voltages to the microcontroler, that's why each time you press the power button on remote the tv respond by turning on. First check the power cord to be well connected in the power-bar and if it's ok...well the power supply is defective and due to the high risk of electric shock i suggest you to call a technicien.
P.S. I respond here because I don't know why our chat session got disconected.
That is the only fuse. Its purpose is not so much to protect the
TV parts but to establish the UL rating by protecting against
overcurrents and fire.
Next thing to check is the B+ voltage (125 to 160Vdc) on the big
electrolytic capacitor near the power entry. No volts here tells
you the problem is before this in the power supply parts. After
here means the high-voltage supply.
Check that and get backl to us.
it is due to vertical section.
in tv there is one control called vertical hold control.
scrolling down the screen will be ok if you adjust it .
if you are not tech.person call tech for help.
as you say that it is 20 years old .
